Do you mean with a load on it. or without? In other words, while the air hammer is pointed downward, if you put (example, the chisel tip) against a surface to be cut/hammered/etc., it doesn't work? Because, under normal circumstances, it won't work while pointed downward unless the chisel tip is actually against something. If it's doing that under load, though, have you checked the chisel you're using? If the shaft of the chisel is broken or marred, it may not be smoothly traveling the way it should. If it's okay, you likely have a broken piston inside.

I think it is leakin air thru the trigger what would cause that


If air is leaking from the trigger, check vinyl ball and oring on the white plastic firing pin. If air seems to leak from the plunger just in front of the trigger (with air connected and nails removed move plunger with finger and listen for change in sound), remove the head and pull out the cylinder. The outer oring to the plate around the cylinder is bad, however, clean the cylinder and lube with white grease. Good luck

This is the izh 513m .177 rifle. It's brand new. I am not sure as of what to do and the hammer want budge and the trigger won't pull. The barrel has no tension and it won't go up like its supposed to.


This could be a factory safety that the hammer and trigger do not move while in the cocked position. The barrel may be locking down purposely. Look near the spring or in the path of the barrel where it folds back up and look for a release button. What do you see?

DeWalt D51823 nailer shoots continusously when plugged into air hoswe


Shooting continusously caused by worn orings in the trigger valve and in the gun.Dewalt framing nailers use some vinyl orings (gold or clear in color) that fail too soon in both the trigger and the cylinder spacer (white plastic). Air out the nose of gun indicates air is leaking past the cylinder spacer seals (If piston is pushed down with air leak then headvalve seal is leaking (remove nails for this test)). If piston is not pushed down with leak, remove head and pull out the cylinder with cylinder spacer (white plastic). Place the cylinder on workbench with bottom up. Push down on locking ring and remove retainer to release all the other parts. Take picture or take note of parts together and as you pull them off to aid in re-assembly. You will need to replace the two orings between the white cylinder spacer and the cylinder. Order oring kit from dewalt or just purchase one ( # 141 universal oring ) and one metric oring 74.4mm x 3.1mm from hydraulic parts store. If the piston was pushed down with air leak, replace headvalve orings in the head. The trigger valve also has vinyl orings on the trigger pin. You could try replacing the orings but hard to find . Pin uses 2mm x 1.5mm. The orings on the inner valve should fit snuggly on the outer contact surface. If the valve just falls out the the body, the orings are too loose or the body is worn. I would just replace the trigger valve to be safe, however repaired works ok if you can find the orings. Trigger orings do not come in the kit. I would also remove the nails after each use and only reinstall them after air is connected and gun seems to work as it should. The Good luck with your repair.

My new porter cable RN175B nail gun won't discharge a nail


If the trigger is set to single fire, you will need to place the gun against the work then pull trigger as you have done. Try setting the trigger to bump fire and try again. If hear a thump inside the gun, remove the head and check that the head valve in not stuck from lack of lubrication. Easy test, remove the nails, remove trigger pin, remove trigger and manually push trigger firing valve. If the gun fires then suspect faulty trigger or safety arm not lifting enought to activate the trigger valve. Good luck

I have the 2 1/2 Hitachi for nailing siding. The nail gun had not been used for a couple of years, but now will only drive the nail half way in. Sounds like an air leak when driving the nail. I have...


Remove the nails and air supply. With side door open notice position of driver. Driver should be at top position with tip not visible. If driver is down and it moves within cylinder when you tilt nose up then down again, time to replace orings. If driver is down, it should extend past the nose about 1/4 inch (if driver is broken at the tip the end will look rough and nail will not drive in all the way). If driver extends past the nose more than 1/4 inch then lower bumper may be breaking up /cracked. Easy test for proper function. With nails removed and side door open, connect air to gun and dry fire gun against hard rubber or old coiled air-hose (with air connected and trigger depressed, no air should leak from trigger area, if air leaks when trigger is depressed, look for fault at trigger pin). Feeder should move back then forward in quick motion almost matching speed of driver and driver should not creep down between shots. No air should leak from nose of the gun (push nose against hard rubber and depress trigger and hold in this position, driver should stay down with very little or no air leaking out of nose, when you release trigger, driver will return). If air leaks out of nose while holding in this position, replace lower bumper. If a quantity of air leaks from valve in front of trigger, cylinder orings may need replacing or outer part of cylinder has fine scratches (remove scratches with 400 grit paper). Parts are available at www.toolpartsdirect.com. Good lucki

I own about a one year old Bostitchmodel BT1855 18 ga nailer. When I pull the trigger I hear the compressed air but the hammer does not come down and drive the nail.


Usually when you hear the pop of the compressed air and the driver does not move indicates that the driver blade is bent, broken, or stuck due to debris. Remove head and pull cylinder to examine. Parts are not expensice and are available as kit including driver and cylinder with related parts or just the driver. from WWW.bostitch.com or even ebay. If driver is bent, you can probably make adjustment and get more life. Good luck

As I try to fire the gun, I just get a small thump of air and no nail fires This gun is 2 years old and worked perfectly when I put it away last spring.


Problem you describe is typical of stuck driver or firing valve. Easy to check; remove head and make sure piston moves down cylinder (upon removing head, piston should be at top). Your gun utilizes sliding cylinder instead of moving valve in head. When you pull the trigger the cylinder moves down allowing air pressure to drive piston down. Orings swell overtime which prevents the cylinder from moving/firing. If cylinder does not move down/up, may be time for rebuild kit. Parts are available at dewalt service center or can be ordered from www.toolpartsdirect.com. Good luck

Hi, i got a hitachi nv45ab and My nailer leaks air out the back


Hitachi nv45 series is the most popular line of nailers amoung professional roofers. There are three areas that develop leakes. Leak out head vent indicates cylinder stuck in lower position or headvalve worn. With air connected, gently rap head of gun against rubber mat to move cylinder to position. (Use caution not to damage head). If this action works, gun needs cleaning internally or lack of oil. If air still leaks out vent remove head and examine valve in head and replace as needed. Check that cylinder moves freely up/down (travel aprox 1/4"). If cylinder is hard to move pull cylinder and clean replacing orings as needed. If leaking around trigger, remove rollpin and trigger and check nylon ball for pits and replace as needed. If leaking around base of gun check for loose bolts and/or worn gaskets. Remove nail canaster to check feed piston gasket and screws. Good luck with your repair and post again if you have other question.

335 while using suddenly went exessive speed soswitched off now wont run at all


Excess uncontrolled speed is either a severe air leak between the carburetor and the cylinder, or the throttle mechanism is jammed by something--usually the trigger assembly is full of sawdust or dirt. Remove the air cleaner from the carburetor so that you can observe the short throttle arm on the carburetor. Pull the trigger and release--the arm should move to the full throttle limit projection on the carburetor body, then fall back to the idle speed screw when released. If it hangs in between either position and nothing around the carburetor is causing such (such as a damaged return spring at the arm), then open the trigger mechanism in the handle and clean out any debris. Make sure to note the position of all parts. If nothing appears to be amiss, then try to move the carburetor body--any apparent movement should be investigated. Some saws use a rubber isolation device that prevents vibrating the carburetor during operation, and these sometimes will crack the rubber sleeve or seals causing excess air leakage. If damaged in any way, replace it. Other problems could include a broken screw holding the carburetor in place. Hope some of this helps!

Cannot load staples


At the back of the staple gun is a flat shaped metal piece. It's at the bottom. Push in, pull down, then pull the mechanism out. You'll see it's a metal rod with a spring, that is attached to that flat metal piece. The spring pushes against another flat metal piece, that has a hole in it, and travels back, and forth on the rod.

The flat metal piece that the spring pushes down the rod, pushes against the staples.

Remove this spring mechanism, slide the staples down the rails. The staples will be in the position of an upside down U. Replace the spring mechanism, and lock it back into place. (Push in, pull up)

Should, your question be in reference to the fact that you have staples loaded, but upon pressing the trigger nothing comes out:

In the front of the staple gun, is a flat metal piece that pushes down on the staples. One staple at a time. The flat metal piece is shoved down by spring pressure. The spring pressure is applied to the flat metal piece each time you squeeze the trigger. (Flat metal piece = Hammer)

Sometimes, Two staples try to come out. When they do, this flat metal hammer is stuck up in the gun. To free the flat metal hammer, remove the spring mechanism out of the back of the staple gun. (The spring mechanism discussed above) Remove any staples in the gun.
Try to use a flat blade screwdriver, and see if you can shove the flat metal hammer in the front of the gun -> UP.
(DO NOT have the staple gun pointing at your face! DO NOT squeeze the trigger! DO NOT use excessive force)

If this method is of no avail for you, you have to disassemble the gun, and remove the metal hammer, and stuck staple/s.
